Ignore question 1 I need help on #2 please this homework is due next period

Step-by-step explanation:

here's your solution

==> by using Pythagoras theorem

==> base^2 = hypotenuse^2 - perpendicular^2

==> hypotenuse = 18 , perpendicular = 16

==> base^2 = 18^2 - 16^2

==> base^2 = 324 - 256

==> base^2 = 68

==> base = √68

==> base = 8.24

Answer:

The first step is to determine the largest number that evenly divides the numerator and the denominator (also called the Greatest Common Factor of these numbers). In other words, what's the biggest number that goes into '2' (the numerator) and '4', the denominator?

Step 2. Once you've answered step 1 and realized that, for our fraction at least, the greatest number that evenly divides 2 and 4 is '2'. Now divide the top and the bottom by 2 to get your simplified fraction which is ½.

I hope this helps if you have any questions on my answer plz let me know Ty :3

Answer:

find the greatest common factor, then divide the bottom and the top, and you have that as your answer

hope this helps

have a good day :)

Answer:

Step-by-step explanation:

in complementary angle, the sum of two angle is always 90 degree.

let another angle be x

x+78.7=90

x=90-78.7

x=11.3

therefore anothere angle is 11.3 degree.

The equation of the red graph is,

⇒ y = x² + 4

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The equation of blue graph is,

⇒ y = x²

Since, We have;

The red graph is 4 unit up from the blue graph.

Hence, The equation of the red graph is,

⇒ y - 4 = x²

⇒ y = x² + 4

Therefore, The equation of the red graph is,

⇒ y = x² + 4

Answer:

Given, ∠MNP=107 degree.

Therefore, ∠QPN= 107 degree. [as, MN=PQ]

We know, sum of four angles of a quadrilateral is 360 degree.

And as MN=PQ, ∠NMQ=∠MQP.

Therefore, ∠MQP= {360 degree-( 107degree+ 107 degree)}/2

                             =( 360 degree-214 degree)/2

                            = 146 degree/2

                            =73 degree.

Answer:

t = 5 seconds h = 128 feet

Step-by-step explanation:

The given equation of the object is :

[tex]h(t)=-16t^2+64t+80[/tex] .....1

When it hits the ground,

h(t) = 0

So,

[tex]-16t^2+64t+80=0\\\\t=-1\ s\ and\ t=5\ s[/tex]

The object will hit the ground in 5 seconds.

Now, put t = 1 s in equation (1).

[tex]h(1)=-16(1)^2+64(1)+80\\\\h(t)=128\ ft[/tex]

The object is at a height of 128 ft at 1 second.

The value of {b}, that is the slope of the line is equivalent to 1/9.

The general equation of a straight line is → y = mx + c.

Given is a graph as shown in the image attached.

The given line has the coordinates mentioned below -

A(7, 22)

B(25, 24)

We can write the slope as -

{m} = (y₂ - y₁)/(x₂ - x₁)

{m} = (24 - 22) (25 - 7)

{m} = 2/18

{m} = 1/9

Therefore, the value of {b}, that is the slope of the line is equivalent to 1/9.

Answer:

The answer is (13,48,50)

Answer:

4 and 9

Step-by-step explanation:

here's how it should be:

(36÷4) - (36÷9)

9 - 4

5

Answer:

(36 ÷ 4) − (36 ÷ 9) = 5

Step-by-step explanation:

To solve, we need to find the quotient of 36 divided by each number listed:

 ║12 ⇒ 36 ÷ 12 = 3

 ║8 ⇒ 36 ÷ 8 = 4.5

 ║9 ⇒ 36 ÷ 9 = 4

 ║4 ⇒ 36 ÷ 4 = 9

So, which of these two numbers can you subtract from each other to get 5?

 ║We can subtract 4 from 9 to get 5.

Therefore, our answer should be:

 ║(36 ÷ 4) − (36 ÷ 9) = 5

Answer:

$1.26

Step-by-step explanation:

So you just have to find 2.25% of 56.

To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:

2.25% of 56

Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:

2.25% × 56

Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.

2.25% = 0.0225

And now you have:

0.0225 × 56

Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.

But once you multiply 0.0225 × 56, you get an answer: 1.26
